title = "Nonlinear dye-doped liquid crystals for fast and broadband CW and long-pulse laser power control and switching",
abstract = "We present a theoretical model and some experiment demonstrations of all-optical passive switching processes with 90° twist-aligned nano-doped nematic liquid crystal cells sandwiched between two crossed polarizers. The photosensitive dopants give rise to laser induced dye-assisted director axis reorientation and order parameter modifications, which in turm produce an intensity dependent polarization switching and hence a transmission modulation capability. Experimental observations are in good agreement with our expectation derived from modified Jones matrix analysis and also demonstrate the feasibility of an efficient [microwatt power] low threshold polarization and fast switching [microseconds] all optical limiting device for visible as well as infrared lasers or bright light sources.",
